{"id":"CVE-2026-2917","state":"PUBLISHED","title":"Happy Addons for Elementor <= 3.21.0 - Insecure Direct Object Reference to Authenticated (Contributor+) Post Duplication via 'post_id' Parameter","description":"The Happy Addons for Elementor plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.21.0 via the `ha_duplicate_thing` admin action handler. This is due to the `can_clone()` method only checking `current_user_can('edit_posts')` (a general capability) without performing object-level authorization such as `current_user_can('edit_post', $post_id)`, and the nonce being tied to the generic action name `ha_duplicate_thing` rather than to a specific post ID. This makes it possible for authenticated attackers, with Contributor-level access and above, to clone any published post, page, or custom post type by obtaining a valid clone nonce from their own posts and changing the `post_id` parameter to target other users' content. The clone operation copies the full post content, all post metadata (including potentially sensitive widget configurations and API tokens), and taxonomies into a new draft owned by the attacker.","publishedAt":"2026-03-11T07:36:25.496Z","updatedAt":"2026-04-08T17:09:21.829Z","severity":{"score":5.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["thehappymonster Happy Addons for Elementor"],"affected":[{"vendor":"thehappymonster","product":"Happy Addons for Elementor","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.21.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/9234b1ce-032f-487d-b60a-f80c78373238?source=cve","https://plugins.trac.wordpress.org/browser/happy-elementor-addons/tags/3.20.7/classes/clone-handler.php#L21","https://plugins.trac.wordpress.org/browser/happy-elementor-addons/tags/3.20.7/classes/clone-handler.php#L61","https://plugins.trac.wordpress.org/browser/happy-elementor-addons/trunk/classes/clone-handler.php#L21","https://plugins.trac.wordpress.org/browser/happy-elementor-addons/trunk/classes/clone-handler.php#L61","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3475242%40happy-elementor-addons%2Ftrunk&old=3463375%40happy-elementor-addons%2Ftrunk&sfp_email=&sfph_mail="],"weaknesses":["CWE-639"],"ingestedAt":"2026-10-29T20:11:31.369Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/2xxx/CVE-2026-2917.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-2917","state":"PUBLISHED","datePublished":"2026-03-11T07:36:25.496Z","dateUpdated":"2026-04-08T17:09:21.829Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-02-20T20:58:53.545Z"},"containers":{"cna":{"title":"Happy Addons for Elementor <= 3.21.0 - Insecure Direct Object Reference to Authenticated (Contributor+) Post Duplication via 'post_id' Parameter","descriptions":[{"lang":"en","value":"The Happy Addons for Elementor plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.21.0 via the `ha_duplicate_thing` admin action handler.
